Cybersecurity can be complex, especially when it comes to understanding standards and maintaining compliance. To simplify the journey, we’ve created The Ultimate NIST Handbook, a practical guide to key NIST standards shaping information security best practices.
What’s Inside?
This handbook is tailored for professionals and includes:
- NIST Standard Numbers & Titles for quick reference
- Clear Descriptions to explain the purpose and scope of each standard
- Direct Links for easy access to critical resources
Whether you’re new to InfoSec or an experienced expert, this handbook is your go-to resource for strengthening your security framework and staying on top of compliance.
You Should Know:
Key NIST Standards & Their Applications
- NIST SP 800-53 – Security and Privacy Controls for Federal Information Systems
– Command to check compliance on Linux:
sudo lynis audit system --check-compliance
– Use OpenSCAP for automated compliance checks:
sudo oscap xccdf eval --profile xccdf_org.ssgproject.content_profile_nist-800-53 --results scan_results.xml /usr/share/xml/scap/ssg/content/ssg-rhel8-ds.xml
- NIST SP 800-171 – Protecting Controlled Unclassified Information (CUI)
– Verify system hardening with:
sudo grep -i "password" /etc/login.defs
– Check SSH security settings:
sudo sshd -T | grep -i "permitrootlogin"
- NIST Cybersecurity Framework (CSF) – Risk Management Guidelines
– Use `nmap` to assess network vulnerabilities:
sudo nmap -sV --script vuln <target_IP>
– Monitor logs for anomalies:
sudo tail -f /var/log/auth.log
4. NIST SP 800-61 – Incident Response Guidelines
- Isolate a compromised system:
sudo iptables -A INPUT -s <malicious_IP> -j DROP
- Capture network traffic for forensic analysis:
sudo tcpdump -i eth0 -w incident_capture.pcap
What Undercode Say:
NIST standards are essential for cybersecurity professionals, providing structured frameworks for risk management, compliance, and incident response. Implementing these standards requires hands-on knowledge of security tools, log analysis, and system hardening.
- Linux Security Commands:
sudo chmod 600 /etc/shadow Restrict sensitive file access sudo auditctl -w /etc/passwd -p wa -k passwd_changes Monitor password file changes
Windows Security Commands:
Get-WinEvent -LogName Security -MaxEvents 10 Check recent security events secedit /export /cfg sec_policy.inf Export security policy
